The Ford Barn

My shutoff valve looks like all the ones in the catalogs, so I assume it is a late model replacement for the original. I shut it off faithfully after each trip (in and out of the garage) but the carb is still covered with gas, and it drips on the floor. I am inclined to get a hardware store ball valve with brass fittings to the flared gas line. Les Andrews says the valve is 1/2" NPT, but mine measures about 0.550" male thread OD, or closer to 3/8" NPT. Do I have an oddball or is Les wrong? I prefer to have the correct replacement in hand before removing the leaker.
